Hi my Jaguar x300 3.2 6cyl drive very good but took it for a 100 mile motorway run and after 60 miles started missing and got worse and I got it home and after 8 hours I took it for a 5 mile drive of upto 60 miles per hour and it drove faultless I hope you can help thanks

 

/The face of the crankshaft position sensor cleaned as well as the connector ?

 

Thank you I'll check that out much appreciated

 

Is it possible you got some contaminated fuel before you left on the trip?

Have you scanned the ECUs for any stored diagnostic trouble codes?

Cheers,

Don

 

Hi yes my stepfather is a retired mechanic and he said it could have been bad fuel and I am going to get the codes checked no more supermarket fuel for my cars anyway thanks for your reply Don cheers Scott

 

The CEL codes for the X300 can be found on page 111 or 121 depending on year

Thanks for your help I am getting the ecu read tomorrow hopefully it has the problem on their thanks again

 

In the states the auto parts stores will read them for free as they want to sell you the repair parts

I don't know how they do it in England

 

Hi there as far as I know in England you have to pay a garage to read the ecu tomorrow will be the moment of truth hopefully it is stored on the ecu otherwise I will have a big head ache trying to sort it out if I was in my native NewZealand my stepfather would sort it in no time lol 😂 cheers mate

 

make sure you write down the numbers and don't rely on memory

I fail to remember them all myself

One of interest is the P0335 on page 111 or 121 of the doc provided for the crankshaft position sensor

This code alot of times does not show even though the item is defective

There is a code P0340 for a separate Camshaft position sensor that is only used in the starting sequence

Easy to get them mixed up , ask me how I know

Make sure after you write down the codes you have them reset or cleared

 

Hey there I changed my fuel filter and it still misfired dag nab it but then got a new coil and one new plug and went the cylinders one by one and on the last one it worked now jag running like a Swiss watch very happy thanks
